Secondary Syphilis in a 43-Year-Old Adult Man

Résumé fourni par la source

We report a case of secondary syphilis simulating Gibert's pityriasis rosé. The patient was a 43-year-old adult with no previous history of syphilis. Erythematous circumscribed plaques were located on the abdomen, back and limbs, with characteristic palmar-plantar involvement. Histological examination was non-specific. Diagnosis was based on the positivity of treponemal tests. The patient's condition improved after administration of two doses of benzathine penicillin.
